AttackFlash
If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing.

Stormfront is a set in the Diamond & Pearl series. It was released on 1 November 2008. The printed size is 100. This checklist is longer, at 106 cards. Electrode is 37/100, in position 37 of 106 on this checklist. Before it is 36 Electrode, and after it is 38 Farfetch'd. The listed rarity is Uncommon.
Electrode is a Stage 1 Lightning Pokémon with 80 HP. The card lists level 45. In the Pokédex this is Electrode (#101), generation 1 (Kanto). The card says it evolves from Voltorb. In this catalog that name is Voltorb (#100).
Sumiyoshi Kizuki illustrated this card. The same name is on 212 other cards in the catalog.
Electrode (#101) has 45 other cards in the catalog. Those other cards are in 40 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Electrode 21/102 in Base (1999). Both list 80 HP. The rarity there is Rare, and here it is Uncommon. Keiji Kinebuchi illustrated that card, and Sumiyoshi Kizuki illustrated this one. 39 other cards of Electrode list a different HP.
The attack Flash lists 20 damage. The cost is Lightning. If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing. Electro Diffusion is another attack lists 40+ damage. The cost is Colorless, Colorless. Does 40 damage plus 10 more damage for each Lightning Energy attached to Electrode. Flip a coin. If tails, discard all Lightning Energy attached to Electrode. Weakness is Fighting +20. Resistance is Metal -20. The flavor text reads "It is known to drift on winds if it is bloated to bursting with stored electricity."
I keep a set binder for Stormfront, meant to hold every card of that set. This card is one slot in the Stormfront set binder. A generation binder holds one card of each species. Electrode can fill a slot in Generation 1 binder (Kanto). I still need this card.
